Spool insulators, known in industry slang as pineapples, dead-end or support secondary voltage conductors in electrical utility applications. Used with spool bolts, clevises, and secondary racks, these components accommodate conductors through their grooved exterior and central mounting hole, enabling secure attachment in both horizontal and vertical positions on utility neutral and secondary lines.<\/p>\n

Wet-process porcelain construction provides resistance to moisture, corrosion, and chemicals through a vitrified and glazed surface. The thoroughly mixed and fired porcelain prevents fractures or glaze imperfections, with a sound, smoothly finished body ensuring long-term reliability in overhead power distribution systems.<\/p>\n

Technical specifications comply with American National Standards Institute (ANSI) C29.5 and class designations 53-1, 53-2, and 53-3. Minimum ultimate tensile strengths range from 2000 to 3000 pounds depending on model. Low frequency dry flashover voltages span 20 to 35 kilovolts, while wet flashover performance varies from 8 to 18 kilovolts vertically and 10 to 25 kilovolts horizontally. Standardized dimensions include heights from 54 to 105 millimeters, diameters from 57 to 105 millimeters, and an 18-millimeter central hole diameter for mounting hardware compatibility. Weights range from approximately 0.2 to 1.2 kilograms per unit.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
